::::::I challenge you to find a comic in the archive that can't be twisted to say it's related to COVID-19. At this point people are finding connections in the same way that people analyze "the curtain is blue".

I'm concerned that, with "Precise Number" there's the usual confusion between Accuracy and Precision (''edit: and of course Resolution, too!''). A precise number can still be utter garbage, as 84.7489327(646475)% of all mathematicians could tell you.

:The table of formulae for the propagation of variance σ addresses that aspect. You can't know the accuracy of a result without knowing the precision of its calculation, and while reducing precision always reduces accuracy, it's not the other way around. But precision is inherent in the representation and operations, while accuracy is secondary when you aren't discussing the initial measurements of the inputs, so I think the terminology is correct. | :The table of formulae for the propagation of variance σ addresses that aspect.

− | :By the way, shout out to [https://www.explainxkcd.com/wiki/index.php?title=2295%3A_Garbage_Math&type=revision&diff=190882&oldid=190870 172.68.51.124] for filling out all but one of those table entries. I wonder where they looked them up. I'm guessing a ''CRC Handbook'' left over from High School chemistry or some such? Anyway, good job! This really looks classy now that it's been cleaned up a bit.
